Order 47. Halorageoe. 109 



H. calls this small order one quite by itself, but some authorities 

 make it a tribe of Saxifrageae. The stamens he calls almost hypo- 

 gynous. The curious glandular hairs on the leaves is the great out- 

 ward distinction; "the clammy sundew's glistening glands'* being 

 a fatal trap to small flies. Three species are known in Europe. 



DHOSERA. As the order. 



1. D. Burmanii. Stemless, a good deal tinged with red, 

 leaves radical crowded nearly flat on the ground, wedge-shaped 

 or obovate, flowers on a slender scape in a one-sided raceme 

 white, sepals red, pointed, styles 5, undivided. 



2. D. Indica. Stem three or four inches high, simple or 

 branched, leaves alternate linear, fringed with long hairs ; 

 flowers in racemes red or pink, styles 3 bifid to the base. 



I have had these at Dapoli and one or two other places in the 

 Rutnagherry collectorate, and they seem not to occur out of the 

 Konkan in this Presidency, though H. gives them a wide range in 

 India. 



ORDER 47. HALORAGE^l. 



Small plants, often aquatic, with small and inconspicuous 

 flowers, calyx lobes and petals 4 or none, stamens 8, 4 or 1, 

 ovary inferior, styles 4, 2 or 1. 



This is the order to which the Mare's tails of English ponds and 

 ditches belong, and is neither interesting, beautiful, nor useful. In 

 many cases the flowers are, as to some of their parts, quite rudi- 

 mentary. 



MYRIOPHYLLUM. Herbs with floating stem and whorled 

 leaves, flowers small, sessile or nearly so. 



* M. Indicum (M. tetrandum, D.) A small water plant, 

 leaves narrow lanceolate, the lower ones divided into many 

 hair-like segments, flowers white, solitary in the axils, upper 

 male, lower female ; all parts of the flower 4, but styles some- 

 times 2. 



Common in tanks (D. and G.}. This is the only species of W. India, 

 although by some authorities Trapa has been put in the order. 



ORDER 48. RHIZOPHORE.E. Mangroves. 



Trees or shrubs, usually but not always, growing in the salt 

 mud of tidal rivers, leaves opposite smooth, with stipules 

 (except one tribe not here mentioned), flowers regular, calyx 

 variously lobed, petals as many, stamens usually double as 

 many : fruit crowned by the calyx, one-seeded.
